Connect only if the user is logged Ubuntu 26 NX 9.4.14

Ubuntu 26.04 NoMachine 9.4.14

The connection occurs only if the user is logged in and the screen is not locked.

How to set this up correctly?

Can you tell us what desktop environment you are connecting to? Logs from the Ubuntu machine would be useful as well. Go to the NoMachine settings on the Ubtunu server, security -> log level debug, restart, reproduce the problem, collect the logs (Take logs from the same Security panel) and share them with us. You can attach here or send directly to forum[at]nomachine[dot]com. In the case of the latter, please use the title of this topic as the subject of your email. Thanks.

Ubuntu 26.04 – desktop – only Wayland

I sent three server log archives by email:
1. Before user login – error
2. After user login, screen locked – error
3. Screen unlocked – successful

 

Thanks.

Hi,

thanks for submitting the logs. It appears there is something wrong with the ‘gdm-greeter’ system user that is used for the login. The debug --collect that is in our logs procedure did not find your home directory and so we have no logs from there. You will need to gather them manually.

By default on Ubuntu 26.04 the home directory should be in /run/gdm3/home/gdm-greeter/. But since something is wrong they might be in another place. The command:

echo ~gdm-greeter

should point to them. We need the whole .nx directory that you find there. Zip that up and send as before 🙂

Can you also tell us if this is a fresh install or is it an update from another version. If it’s the latter, what version were you updating from? Also useful is any journalctl output from the last boot:

journalctl -b -1 > journal.log

Hi,

Ubuntu 26.04 – fresh install

The system user ‘gdm-greeter’ is missing

It sounds more like something is broken on the system OS. There are references in logs to ‘/run/user/60578/’ so this directory has to be present. Maybe you could investigate the user with uid 60578?

[froZZen]

Hi,

It sounds strange, but a user with such an uid 605787 does not exist, and the specified directory(‘/run/user/60578/’ ) does not exist either. Completely clean installation Ubuntu 26.04.

To make sure the NoMachine logs are preserved is to edit the node.cfg file and set the key ‘UsersDirectoryPath’ to a directory that can be accessed by everyone e.g. to the main NoMachine log directory:

UsersDirectoryPath "/usr/NX/var/log/users"

then ensure the directory is available for everyone:

sudo mkdir /usr/NX/var/log/users
sudo chmod 777 /usr/NX/var/log/users

then please restart NoMachine:

sudo /etc/NX/nxserver --restart

and try to connect to Login Window again and collecting logs using

sudo /etc/NX/nxserver --debug --collect

Hi,

I did everything described above, and also updated HX to version 9.5.7, and… everything worked!

Thanks, Britgirl!

So you can now connect without any problems? Good to know.

[froZZen]

It seems to be working as expected.
